Versuchsvorschrift

To a stirred solution of (3-tert-butyl-1-(4-fluorophenyl)-1H-pyrazol-5-yl)methanamine (60 mg, 0.247 mmol, 1.0 eq) in acetonitrile (6 mL) was added TEA (0.136 mL, 99 mg, 0.986 mmol, 4.0 eq) followed by phenyl 3-fluoro-4-((2-hydroxyethoxy)methyl)-phenylcarbamate (76 mg, 0.252 mmol, 1.02 eq.) and stirred at reflux for 16 h. The solvent of the reaction mixture was evaporated and the residue was purified by column chromatography (EtOAc/cyclohexane (1:2)) to get 1-((3-tert-butyl-1-(4-fluorophenyl)-1H-pyrazol-5-yl)methyl)-3-(3-fluoro-4-((2-hydroxyethoxy)methyl)phenyl)urea (83 mg, 73%).
